Home Page Redirect

[futurewebboss]

I have some code I'd like to insert so that it only runs on the home page when the site is loaded. The code detects the type of device being used and if it is a mobile device it will redirect to download a progressive mobile web app. I can't use Genesis Simple Hooks because the code will execute on every page. Does anyone have any suggestions?

Thank You

Dan

You have at least 2 options :

1. Add the code to a home.php or front-page.php file.

2. Add the is_home() or is_front_page() conditional tag to the code.

Hi Brad,
Thanks. Here's the full code. Not sure how or where to add what you're specifying. I was reading about these but not sure how to implement.
Thanks for the reply.

Try adding it to your home page file. You'll need to wrap it in closing and opening PHP tags.

You don't need a conditional tag when adding the code directly to a home or front page template file.

The problem you are having is because PHP is trying to execute the jQuery. When you include scripts conditionally, you either need to wrap only the conditional in PHP tags or echo the script within PHP. To do the first, you need something like this:

<?php
if ( is_home() ) {
?>
<script>
...
</script>
<?php
}
?>

For the second, use something like this:

<?php
if ( is_home() ) {
echo "<script>...</script>";
}
?>

Index.php is obviously not the place for this code. I added the code to genesis simple hooks to execute on the before closing head and am testing that now. You guys were probably assuming such and I'm sorry for wasting anyones time here. Will let you know how it works out.

[futurewebboss]

Ok I put the code (below) in Genesis wp_head Simple hooks and set to execute php at the site dennis-kelly.com and it appears to work flawlessly

[Victor Font]

As Brad said earlier, you need to add the code to your home page file, which is either front-page.php or home.php. Index.php has nothing to do with the home page. WordPress isn't even loaded yet when index.php is called. That's why is_home() isn't working. is_home() is a WordPress conditional.

If you hire a developer, this could be done for you in a few minutes.
